SPECIFICATION forming part of Letters Patent No. 597,752, dated January25, 1898.

Application filed December 24,1896 Serial No. 616,939. (No model.)

To aZZ whom it may concern:

Be it-known that I, EDWARD D. Senna, a citizen of the United States,residing at Providence, in the county of Cecil, State of Maryland, haveinvented a new and useful Improvement in Apparatus for Beating andCleaning "Wood-Pulp, &c., which improvement is fully set forth in thefollowing specification and accompanying drawings.

My invention consists of an improved construction of apparatus forbeating and cleaning Wood-pulp; and it consists, primarily, in a novelconstruction of tank into which the pulp is introduced and means forthoroughly I5 beating or whipping the pulp, for causing a propercirculation to be imparted to the same, and for cleaning said pulp.

It further consists of novel details of construction, all as will behereinafter set forth,

and specifically pointed out in the claims.

Figure 1 represents a plan View, partly in section, on line y y, Fig. 2,of a tank into which the pulp is first conducted, the same beingprovided with devices for whipping or beating and for cleaning the same.Fig. 2

represents a section on line as on, Fig. 1.

Similar letters of reference indicate corresponding parts in bothfigures.

Referring to the drawings, A designates a tank into which the pulp isfirst conducted for the purpose of beating or cleaning the same, saidtank having a bottom B and an open top, near which are located the beamsO.

D designates a shaft which is mounted in suitable bearings located inthe present instance near,,the top of the tank A, said shaft beingactuated by means of power applied to the pulleys E. h

F designates a bevel-gear mounted on the 0 shaft D, said gear being inmesh with the bevel-gear G, which is mounted on the upright shaft I'I,said shaft rotating in bearings J and K, located in the upper and lowerportions, respectively, of the tank A.

5 L and M designate arms projecting laterally from the upper and lowerportions of the shaft H, respectively, said arms having the rods Nextending between the same, it being noted that said rods are in thepresent instance three in number.

P and Q designate arms extending laterally from the shaft H in anopposite direction to the arms L and M, it being noted that said arms Pand Q are shorter in length than the arms L and'M, the former arms beingpro.- vided with the rods R, extendingthcrebe tween, it being noted thatsaid rods are two in number, from which it will be seen that as theheating device N mounted on the shaft H, revolves the pulp contained inthe tank A will be thoroughly disintegrated and commingled, since therods R and M in their rotation will revolve in different planes fromeach other, the rods R cutting the spaces be tween the rods N.

S and T designate upright partitions located Within the tank A,preferablysubstantially parallel to each other, wherebyoverflow-chambers E are formed intermediate said partitions and theouter wall of said tank, the contents of said chambers E beingdischarged through the pipes F. I

U designates cylinder straining devices lo cated in the upper portion ofthe tank A, the same consisting of the closed heads V, the in- 7 5termediate brace V, and the open head X, said head and brace or ringbeing supported upon a shaft Y and said heads having the wire-gauze orsimilar material Z surrounding them, it beingnoted that said cylinders Uare four in number, their relative location being apparent from Figs. 1and 2, and it being apparent that although I have shown said cylindersas supported upon the beams C and partitions S and T they maybesupportedby other means. v

I A designates a pumping device located adjacent the lower portion ofthe tank A, said pumping device having a suction-pipe B communicatingwith the interior of the tank A near its bottom and discharging throughthe outlet-pipe C at the point D into the upper portion of the tank A,whereby it will be seen that during the operation of the pump A and thebeater N the pulp contained in the tank 5 will be thoroughly commingledand whipped, and by the introduction of water into the pipe or pipes Athe pulp will be thoroughly cleansed, the water being permitted to riseup through the gauze cylinders U into the over- [00 flow-chambers E andbeing discharged therefrom into the pipes F, above mentioned.

fibrous material.

The pulp is forced into the tank by any suitable means from a source ofsupply through the pipe L, as shown in Fig. 1, and power having beenapplied to the shaft D the beating device N will be rotated, and thepump A being started it will be apparent that the pulp will bethoroughlyand effectively beaten or forced through the pipes Band G intothe upper portion-of the tank, water being introduced into saidtank bythe pipe A The contents of the tank having been thoroughly commingled,beaten, and whipped and afterward cleansed in the manner described canbe conveyed by any suitable means to any desired point.

It will be apparent that the apparatus may be used for treatingWood-pulp or any other It will of course be understood that changes maybe made by those skilled in the art which will come within the scope ofmy invention, and I therefore reserve to myself the right to make allsuch changes as will come within the spirit thereof.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is-

1. In an apparatus for the purpose set forth, a tank having partitionsforming overflowchambers on the opposite sides of a main chamber, awater-inlet pipe for said main chamber, a beating device in said mainchamber, strainers above said beating device having respectively closedand open ends, and discharge-pipes for said overflow-chambers.

2. A tank having a main chamber and side overflowchambers, a heatingdevice in said main chamber, a series of strainers in said tank abovesaid beating device having closed inner and open outer ends, a pump witha suction-pipe leading from the lower portion of said main chamber andprovided with a discharge-pipe emptying into the upper portion of saidmain chamber, a water-inlet pipe for said main chamber anddischarge-pipe for said overflow-chambers.

. 3. In an apparatus for the purpose set forth, a tank having partitionsforming overflowchambers on opposite sides of a main chamber, aninlet-pipe for the latter, a beating device in said main chamber, saiddevice consisting of a shaft having laterally-projecting arms at itsupper and lower portions, each pair of arms being connected by rods,which latter are adapted to be rotated in different planes, strainersabove said beating device having respectively open and closed ends and adischarge-outlet for said overflow-chambers.
